Log files

Various Storage Mirroring components (Storage Mirroring daemon, Management Console, Failover

Control Center, and the Command Line Client) generate a log file to gather alerts, which are

notification, warning, and error messages. The log files are written to disk. They can be viewed, from

the location where Storage Mirroring is installed, with a standard text viewer.

Each log file consists of a base name, a series number, and an extension.

 Base Name—The base name is determined by the application or process that is running.

 Series Number—The series number ranges from 1 to 999. For example, Storage Mirroring

begins logging messages to

dtlog1. When this file reaches its maximum size, the next log file

will be written to dtlog2. As long as log messages continue to be written, files dtlog3, dtlog4,

dtlog5 will be opened and filled. When the maximum number of files is reached, which by default

5, the oldest file is deleted when the sixth file is created. For example, when dtlog6 is created,

dtlog1 is deleted and when dtlog7 is created, dtlog2 is deleted. When file dtlog999 is

created and filled,

dtlog1 will be re-created and Storage Mirroring will continue writing log

messages to that file. In the event that a file cannot be removed, its number will be kept in the

list, and on each successive file remove, the log writer will attempt to remove the oldest file in

the list.

 Extension—The extension for each log file is .dtl.

1. To modify the maximum file size and the number of Storage Mirroring log files that are

maintained, access the Server Properties dialog box by right-clicking a machine name in the left

pane of the Management Console and selecting Properties.

2. Select the Logging tab.

3. At the top of the window, Folder indicates the directory where the log files are located. The

default is the directory where the Storage Mirroring program files are installed.

4. Modify any of the options under Messages and Alerts, if necessary.

 Maximum Length—Specify the maximum length of the log file. The default size is 1048576

bytes

and is limited by the available hard drive space.

 Maximum Files—Specify the maximum number of log files that are maintained. The default

is 5 and the maximum is 999.

5. Click OK to save the changes.
